    Hi

    I am working on a project and i had to blast up an HP printer for some components.
    I needed a light type of sensor which it actually reads every time it is crossed.
    It seems that is used to read revolutions, a spot is made at a certain point and when it is crossed in the sensor it counts as a revolution.

    I found this sensor in the printer but my problem is that i cannot find the part number or datasheet on how to connect it to use in my project.

    All i need is to know how to connect it so a datasheet or maybe someone knows how to connect it is enough.

    Here with this message there are to pictures of this sensor available. It has 4 pins going out of the sensor.
    Please con someone help me figure them out

    Thanks in advance.

    it is more like a sine/cosine encoder....

    WikiAnswers says:
    Usually these would have four leads coming from them, 2 are for power, the other 2 are outputs from the encoder sensors....
